Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supported on alumina or silica carriers
Prepared catalysts with metal supported on carriers fall under 3815, not base metal powders.
If in petroleum oils as lubricant additive
Molybdenum compounds dissolved in oils classified by oil base in Chapter 27.
If as molybdic acid or salts
Chemical compounds rather than metallic powder go to inorganic chemicals Chapter 28.
